Representations of misogyny in diasporic Chinese Australian writing

This thesis examines the representation of misogyny in literary texts from the beginning of Chinese Australian writing in the late 19th century to the contemporary period. It focuses on the following questions: What is the nature of misogyny in Chinese culture? With successive waves of immigration, do Chinese people take their misogynous ideology and practices to other countries? What form does it take? Where does it originate and how does it evolve over time? How is it presented in literary works? How does misogyny in the host countries differ from that of the native land? How is it presented in literature at different times and from different perspectives, and more specifically, how is it presented in diasporic Chinese Australian writing

Compactly supported solutions to stationary degenerate diffusion equations

AbstractWe consider non-negative solutions of the semilinear elliptic equation in Rn with n⩾3:−Δu=a(x)uq+b(x)up, where 0<q<1, p>q, a(x) sign-changing, a=a+−a− and b(x)⩽0 is non-positive. Under appropriate growth assumption on a− at infinity, we prove that all solutions in D1,2(Rn) are compactly supported and their support is contained in a large ball with radius determined by a. When Ω0+={x∈Rn|a(x)⩾0} has several compact connected components, we give conditions under which there may or may not exist solutions which vanish identically on one or more of the components of Ω0+. For instance, we introduce a positive parameter λ and replace a by λa+−a−. We then show that for λ small, all solutions have compact support and there exist solutions with supports in any combination of these connected components of Ω0+. For λ large and p⩽1 the solution is unique and supported in all of Ω0+. We also prove the existence of the limit λ→∞ of this solution, which solves −Δw=a+wq and lim|x|→∞w(x)=0. The analysis is based on comparison arguments and a priori bounds

Plasmonic Thin Film Solar Cells

Thin film solar cell technology represents an alternative way to effectively solve the world’s increasing energy shortage problem. Light trapping is of critical importance. Surface plasmons (SPs), including both localized surface plasmons (LSPs) excited in the metallic nanoparticles and surface plasmon polaritons (SPPs) propagating at the metal/semiconductor interfaces, have been so far extensively investigated with great interests in designing thin film solar cells. In this chapter, plasmonic structures to improve the performance of thin film solar cell are reviewed according to their positions of the nanostructures, which can be divided into at least three ways: directly on top of thin film solar cell, embedded at the bottom or middle of the optical absorber layer, and hybrid of metallic nanostructures with nanowire of optical absorber layer

Expression of the mismatch repair gene hMLH1 is enhanced in non-small cell lung cancer with EGFR mutations

Mismatch repair (MMR) plays a pivotal role in keeping the genome stable. MMR dysfunction can lead to carcinogenesis by gene mutation accumulation. HMSH2 and hMLH1 are two key components of MMR. High or low expression of them often mark the status of MMR function. Mutations (EGFR, KRAS, etc) are common in non-small cell lung cancer (NSCLC). However, it is not clear what role MMR plays in NSCLC gene mutations. The expression of MMR proteins hMSH2 and hMLH1, and the proliferation markers PCNA and Ki67 were measured by immunohistochemistry in 181 NSCLCs. EGFR and KRAS mutations were identified by high resolution melting analysis. Stronger hMLH1 expression correlated to a higher frequency of EGFR mutations in exon 19 and 21 (p<0.0005). Overexpression of hMLH1 and the adenocarcinoma subtype were both independent factors that related to EGFR mutations in NSCLCs (p=0.013 and p<0.0005). The expression of hMLH1, hMSH2 and PCNA increased, while Ki67 expression significantly decreased (p=0.030) in NSCLCs with EGFR mutations. Overexpression of hMLH1 could be a new molecular marker to predict the response to EGFR-TKIs in NSCLCs. Furthermore, EGFR mutations might be an early event of NSCLC that occur before MMR dysfunction.This work was supported by the National Nature Science Funds in China (Fund No. 81071805; URL: http://isisn.nsfc.gov.cn/egrantweb/), and Dalian Merricon Gene Diagnosis Technology Co., Ltd.

Transcriptome-wide association study reveals novel susceptibility genes for coronary atherosclerosis

BackgroundGenetic risk factors substantially contributed to the development of coronary atherosclerosis. Genome-wide association study (GWAS) has identified many risk loci for coronary atherosclerosis, but the translation of these loci into therapeutic targets is limited for their location in non-coding regions. Here, we aimed to screen the potential coronary atherosclerosis pathogenic genes expressed though TWAS (transcriptome wide association study) and explore the underlying mechanism association.MethodsFour TWAS approaches (PrediXcan, JTI, UTMOST, and FUSION) were used to screen genes associated with coronary atherosclerosis. Enrichment analysis of TWAS-identified genes was applied through the Metascape website. The summary-data-based Mendelian randomization (SMR) analysis was conducted to provide the evidence of causal relationship between the candidate genes and coronary atherosclerosis. At last, the cell type-specific expression of the intersection genes was examined by using human coronary artery single-cell RNA-seq, interrogating the immune microenvironment of human coronary atherosclerotic plaque at different stages of maturity.ResultsWe identified 19 genes by at least three approaches and 1 gene (NBEAL1) by four approaches. Enrichment analysis enriching the genes identified at least by two TWAS approaches, suggesting that these genes were markedly enriched in asthma and leukocyte mediated immunity reaction. Further, the summary-data-based Mendelian randomization (SMR) analysis provided the evidence of causal relationship between NBEAL1 gene and coronary atherosclerosis, confirming the protecting effects of NBEAL1 gene and coronary atherosclerosis. At last, the single cell cluster analysis demonstrated that NBEAL1 gene has differential expressions in macrophages, plasma cells and endothelial cells.ConclusionOur study identified the novel genes associated with coronary atherosclerosis and suggested the potential biological function for these genes, providing insightful guidance for further biological investigation and therapeutic approaches development in atherosclerosis-related diseases

Protection Evaluation of a Five-Gene-Deleted African Swine Fever Virus Vaccine Candidate Against Homologous Challenge

African swine fever virus (ASFV) represents a serious threat to the global swine industry, and there are no safe or commercially available vaccines. Previous studies have demonstrated that inactivated vaccines do not provide sufficient protection against ASFV and that attenuated vaccines are effective, but raise safety concerns. Here, we first constructed a deletion mutant in which EP153R and EP402R gene clusters were knocked out. Based on the deletion mutant, a further deletion from the MGF_360-12L, MGF_360-13L to MGF_360-14L genes was obtained. The five-genes knockout virus was designated as ASFV-ΔECM3. To investigate the efficacy and safety of the ASFV-ΔECM3 virus as a vaccine candidate, the evaluation of the virus was subsequently carried out in pigs. The results showed that the ASFV-ΔECM3 virus could induce homologous protection against the parental isolate, and no significant clinical signs or viremia were observed. These results show that the contiguous deletion mutant, ASFV-ΔECM3 encompassing the EP153R/EP402R and MGF_360-12L/13L/14L genes, could be a potential live-attenuated vaccine candidate for the prevention of ASFV infection

Modeling SNP and quantitative trait association from GWAS catalog using CLG Bayesian network

Genome-wide association studies (GWAS) are a type of genetic methods that have recently received intensive attention. In this paper, we study the construction of the Bayesian network from the GWAS catalog for modeling SNP and quantitative trait associations. Existing methods in the literature can only deal with categorical traits. We address this limitation by leveraging the Conditional Linear Gaussian (CLG) Bayesian network, which can handle a mixture of discrete and continuous variables. A two-layered CLG Bayesian network is built where the SNPs are represented as discrete variables in one layer and quantitative traits are represented as continuous variables in another layer. We propose the method for specifying the CLG Bayesian network, focusing on the specification of the CLG distribution for quantitative traits. We empirically evaluate the construction method, and results demonstrate the effectiveness of our method
